admin c393d8529a R-856: after a crash boot of the host, app mails wait ~15 minutes; a normal boot keeps 90 s (09 decision 143)
The dead-app check (source of app_start_failed and app_stopped_unhealthy) now gates on a crash-aware
boot grace (internal/crashboot): 15 min when the host crash guard's last boot was UNCLEAN and within
30 min of the controller start, otherwise 90 s. The fact is read from the agent's local API
(GET /host/crash-guard, agentapi.Client.CrashGuard). UNKNOWN - no agent, an older agent's 404, no
crash-guard state - is a normal boot. The decision is logged once ("boot grace ...: ... (R-856)").

NEEDS AN AGENT CHANGE to take effect: GET /host/crash-guard serving the guard's state.json fields
(present, last_boot_at, last_boot_unclean, tripped). Until then every box keeps 90 s.
